For example, it is desired to continuously reproduce a plurality of discs without exchanging discs one by one, and the following disc players are known to meet such needs. That is, the disc player is provided with a disc storage section and a reproduction section that are separated from each other, and a disc magazine is detachably mounted in the storage section.

A disc magazine is a case for accommodating a plurality of discs in a stacked manner. An opening for passing a disc is formed at one side edge of the disc magazine. The disc magazine stores the disc inside from this opening, and the disc magazine is mounted in the storage part with the opening facing the reproducing part.

When the user selects a desired disc from the magazine after mounting the disc magazine in the storage unit, the disc moves to the reproducing unit through the opening, and the reproducing unit performs the reproducing operation of the disc. When the reproduction of the disc is completed, the disc moves to the original position of the disc magazine again, and when the user subsequently selects another disc, the disc moves from the magazine to the reproducing unit.
According to such a disc device, a plurality of discs can be stored in the player in advance,
It is possible to continuously play back the disc without frequently changing the disc.

[0005]

However, the following problems have been pointed out in the disc player using the disc magazine. That is, even if one disc is replaced, the disc magazine must be removed from the storage portion side of the disc player, which is very troublesome. Further, a disc player using a disc magazine requires the thickness of the disc magazine itself and a clearance for inserting / removing the magazine, which increases the thickness of the entire apparatus and makes the player larger. Invited.

It is characterized in that these pins are arranged so as to move.

[0012]

The operation of the present invention having the above construction is as follows. That is, when inserting the disc, when the edge of the disc presses the eject pin, the eject pin moves in the disc inserting direction, so that the eject arm moves in the disc inserting direction against the elastic force of the eject arm spring. Therefore, the engaging portion performs a releasing operation to release the engagement between the lever and the eject arm.
By the releasing operation of the engaging portion, the lever receives the elastic force of the lever spring and moves in the disc ejecting direction, and the control arm controls the position of the guide arm according to the movement of the lever. Then, the guide arm moves by the position control of the control arm.

Then, according to the first aspect of the present invention, the guide pin holds the disc between the eject pin and the disc contact portion of the tray. Further, according to the present invention of claim 3, the guide pin holds the disc between the eject pin and the control pin of the control arm. That is, in the present invention,

That is, at least three members contact and hold the disc. Therefore, it is possible to hold the disc from at least three points. Therefore, it is possible to accurately position the disc in the storage portion.

According to the present invention of claim 4,
The discs stored in the tray are conveyed to the reproducing portion side of the disc device through the gap between the guide pins and the eject pins, so that the discs are conveyed to the reproducing portion. Further, the direction of inserting / removing the disc into / from the storage portion and the direction of transporting the disc from the storage portion to the reproducing portion can be shifted. That is, when viewed from the direction of inserting / removing the disk into / from the storage unit, the storage unit and the reproducing unit can be arranged in a skewed manner. As a result, the present invention can reduce the size of the disc device as compared with the case where the storage unit and the reproducing unit are linearly arranged when viewed from the direction in which the disc is inserted into and removed from the storage unit.

In the present invention as described above, even if one disc is replaced, the disc can be directly inserted into and ejected from the tray. Further, since a spring that biases each member in one direction is used as a member that drives the lever, the guide arm, and the eject arm, a drive source such as a drive motor and a drive force transmission system are unnecessary.

Further, an eject arm spring 17 is installed between the eject arm 7 and the tray T. The eject arm spring 17 biases the eject arm 7 so that the eject pin 7b retracts. By the way, if the disc player is placed vertically, when the edge of the CD comes into contact with the eject pin 7b,
The weight of the CD will hang on the eject pin 7b.
At this time, the spring force of the eject arm spring 17 is set so that the eject arm 7 does not rotate counterclockwise in the figure due to the weight of the CD.

[Operation of the Embodiment] The operation of the present embodiment having the above-described structure is performed in the standby state in which the CD is not stored in the storing portion Q, the storing operation for storing the CD in the storing portion Q, the storing of the CD. The following description will be divided into four states, that is, a transport operation of loading and unloading from the section Q to the playback section P and a discharging operation of discharging the CD from the storage section Q.

Standby state: FIG. 1 In the standby state, the stopper portion 4c which is an "engagement portion"
And the hook portion 7c are in an engaged state. Since the elastic force of the eject arm spring 17 tries to rotate the eject arm 7 in the clockwise direction in the figure around the support shaft 7a, the stopper portion 4c acts to push the hook portion 7c forward. On the other hand, the elastic force of the lever spring 14 acts to push the lever 4 backward. Therefore, when the stopper portion 4c and the hook portion 7c are in the engaged state, the elastic forces of the eject arm spring 17 and the lever spring 14 are in balance and the lever 4 and the eject arm 7 cannot move.

In the control arm 6, the regulating pin 6a has the lever 4
Since it is restricted by the cam groove 4b, the control arm 6 does not rotate as long as the lever 4 does not move.
Since the regulation pin 6b is located at the end of the regulation groove 10 on the W2 side, it does not interfere with the insertion of the CD from the opening 3.

The guide arm 5 receives a force in the lower right direction in the figure due to the elastic force of the guide arm spring 15, and the attack portion 6c of the control arm 6 hits the pressing portion 5c of the guide arm 5, but the control arm 6 rotates. Therefore, the guide arm 5 is stopped at that position. At this time, the guide pin 5 a of the guide arm 5 is located in the horizontal portion 9 a of the restriction groove 9.

Storage Operation FIGS. 2 to 4 a. When the CD is inserted into the tray T side from the opening 3 from the state shown in FIG. 1, the edge of the CD pushes the guide pin 5a along the regulation groove 9 and the guide arm 5 starts moving to the left. To do. At this time, since the guide pin 5a is located in the horizontal portion 9a of the regulation groove 9, the guide pin 5a can be smoothly moved to the left.
Further, since a force is applied to the guide arm 5 in the lower right direction in the figure by the guide arm spring 15, the guide pin 5a moves without separating from the edge of the CD. That is, the guide pin 5a first moves leftward as it approaches the diameter portion of the CD (moves from the solid line to the dotted line in FIG. 2), and the CD
It returns to the right as it moves away from the diameter part (moved from the dotted line to the solid line in FIG. 2). Further, the CD is inserted into the tray T1 side while the edge thereof contacts the disk contact portion 8. Further, the disk contact portion 8 presses the edge of the CD from the right direction.

Finally, in the state shown in FIG. 2, the pressing portion 5c of the guide arm 5 comes close to the attack portion 6c of the control arm 6 and presses the CD from the front, and the guide pin 5a moves the CD in the state shown in FIG. Hold the edge of from behind.

Further, the eject pin 7b of the eject arm 7 contacts the edge of the CD. At this time, the spring force of the eject arm spring 17 is set so that the eject arm 7 does not rotate in the counterclockwise direction in the figure due to the weight of the CD, so that the eject pin 7b does not move.
The edge of the CD can be held from the front at the position shown in FIG. Thus, in the initial state of storage, the guide pin 5a,
A total of three members, the eject pin 7b and the disc contact portion 8, hold the edge of the CD from three directions. At the above position, a part of the CD projects outward from the opening 3.

In the state of being stored ... FIG. 3 The CD held at the position shown in FIG. 2 is pushed in the Y1 direction to eject the eject arm spring 1 from the eject arm 7.
When an external force stronger than the spring force of 7 is applied, the edge of the CD presses the eject pin 7b downward (Y1 direction) in the figure, and the eject arm 7 starts rotating counterclockwise in the figure around the support shaft 7a. . Therefore, the hook portion 7c comes off the stopper portion 4c. Once the hook 7c to the stopper 4c
If it comes off, lever 4 will work even if there is no external force from the CD.
Receives the spring force of the lever spring 14 and moves backward (Y2 direction).

When the lever 4 is retracted, each member is brought into a state as shown in FIG. That is, the restriction pin 6d moves to the right by the cam groove 4b. Therefore, the control arm 6 rotates counterclockwise in the figure around the support shaft 6a, and the attack portion 6c also rotates counterclockwise in the figure. As a result, the attack portion 6c releases the restriction force applied to the pressing portion 5c.

Then, the guide arm 5 is moved to the right by the spring force of the guide arm spring 15. Therefore, the guide pin 5a moves along the horizontal portion 9a of the restriction groove 9,
The CD is moved forward, and the slide pin 5b is locked in the regulation groove 11
Move to the right along. When the guide arm 5 moves, the contact portion 5c pushes the attack portion 6c.

Therefore, the control arm 6 is the guide arm 5
It also rotates counterclockwise by the moving force of. Further, the rotation of the control arm 6 causes the restriction pin 6b to move into the restriction groove 10
Move to the left in the figure along.

Further, the guide hole 4f of the lever 4 pushes the arm pin 7d and the taper portion 4g pushes the hook portion 7c. As a result, the eject arm 7 rotates counterclockwise in the drawing around the support shaft 7a.

Storage completed state ... FIG. 4 The storage operation of the CD in the storage portion Q is completed in the state shown in FIG. The position of this CD is the storage position. When the CD is in the storage position, each member takes the following states. That is, the end surfaces of the guide grooves 4d and 4e of the lever 4 come into contact with the support shaft 6a of the control arm 6 and the support shaft 7a of the eject arm 7. These support shafts 6a and 7a regulate the backward movement of the lever 4. As a result, the lever 4, the control arm 6, and the eject arm 7 stop at that position. If the control pin 6 comes into contact with the edge of the CD at the time when the control arm 6 stops, the CD is supported at four points, but may be separated from the edge of the CD. In this case, the pin 6b has only a double insertion preventing function described later.

When the guide arm 5 moves to the right in the figure, the guide pin 5a comes into contact with the edge of the CD. The guide pin 5a receives the spring force of the guide arm spring 15 and pushes the edge of the CD to the right in the figure. Further, when the guide arm 5 moves, the contact portion 5c pushes the attack portion 6c of the control arm 6 to the right in the figure, so that the regulation pin 6b pushes the edge of the CD to the left in the figure. Further, the eject pin 7b of the eject arm 7 is connected to the eject arm spring 17
The edge of the CD is pushed upward by receiving the spring force of. As described above, the four members of the pins 5a, 6b, 7b and the disk contact portion 8 hold the CD in the completely stored state.
Further, in this example, the pins 5a, 6b, 7b are arranged such that adjacent pins form an angle of approximately 120 degrees when viewed from the center of the CD. Therefore, the pins 5a, 6b and 7b can hold the CD from the ideal three points with respect to the CD in the storage position. Further, as the function of the regulation pin 6b, the CD at the storage position is externally shocked,
It plays the role of a stopper when a force is applied upward in the drawing to move in the ejecting direction and the role of a stopper when another CD is inserted from the outside (double insertion preventing function).

For example, when the CD in the storage position is going to move upward in the figure due to a shock or the like, the edge of the CD pushes up the guide pin 5a in the upper left direction in the figure. Guide arm spring 1 rather than this pushing force
If the spring force of 5 is stronger, the CD will not move and there will be no problem. Even when the force pushing up the guide pin 5a exceeds the spring force of the guide arm spring 15, the spring force of the lever spring 14 is always applied to the control arm 6 via the lever 4, so that the force of the lever spring 14 is applied. CD does not move upward in the figure unless it exceeds.

When another CD is about to be inserted on the same tray T, the control pin 6b of the control arm 6 is sandwiched between the CD already stored and the CD inserted from the outside, and the control arm 6 is inserted. 6 cannot rotate in the clockwise direction in the figure, and the restriction pin 6b attached to the control arm 6 can prevent the insertion of another CD.

[Conveying Operation] FIG. 5 FIG. 5 shows the CD storage position in the storage section Q and the CD reproduction position in the reproduction section P. In the disc player adopting the present embodiment, the CD is conveyed by the conveying force of the conveying roller 2 during this period. First, the operation of loading a CD from the storage position to the playback position will be described. As already described in the outline of the disc player, when the user selects a desired CD, the traverse plate 1 and the transport roller 2 are first moved up and down, and the transport roller 2 is moved to the CD side by the movable supporting portion to mount the CD. . And the transport roller 2
With the rotation of 0, the CD is moved from the storage portion Q to the playback portion P.

Since the eject pin 7b always receives the spring force of the eject spring 17 to obtain a force for pressing the CD, when the CD moves, the eject arm 7 moves to C
Starting to rotate counterclockwise in the figure along the edge of D,
After that, when passing the diameter portion of the CD, it rotates in the clockwise direction in the drawing. Then, when the eject pin 7b hits the positioning arm 20, the eject arm 7 stops rotating. That is, the positioning arm 20 holds the eject arm 7 at this position. In addition, in the state shown in FIG. 4, the eject arm 7 is positioned by the positioning arm 20.
Although it could rotate without hitting, the ejecting arm 7 and the positioning arm 20 are in contact with each other in FIG. 5 because the transport roller 2 is moved to the storage part Q side by the movable supporting part.

Further, since the guide pin 5a also receives the spring force of the guide arm spring 15 to obtain a force in the direction of pressing the CD, the guide arm 5 moves when the CD moves.
Starts to move upward in the figure along the edge of the CD, and then moves downward in the figure when passing the diameter portion of the CD. Then, when the contact portion 5c of the guide arm 5 hits the attack portion 6c of the control arm 6, the guide arm stops moving. That is, the control arm 6 holds the guide arm 5 in this position. The dotted line in FIG. 5 shows the positions of the guide arm 5 and the eject arm 7 at the diameter portion of the CD.

When the CD is moved from the reproduction position to the storage position, a C is applied to the guide pin 5a of the guide arm 5 and the eject pin 7b of the eject arm 7 which are held.
The edge of D hits, and then the edge of CD is spread by the guide arm 5 and the eject arm 7. And
When passing the diameter part of the CD, the guide arm spring 15
And the eject arm spring 17 starts to narrow. That is, the CD smoothly returns to the storage position in the tray T while receiving the spring force of both springs 15 and 17.

[Ejection Operation] ... FIG. 6 When the CD is in the storage position on the side of the storage portion Q, the lever 4 is pushed downward by a certain amount to eject the CD. That is,
When the lever 4 in the state shown in FIG. 4 is pushed downward in the figure, the control arm 6 is rotated in the clockwise direction in the figure about the point of the support shaft 6a by the cam groove 4b of the lever 4. At the same time, the attack portion 6c of the control arm 6 pushes the contact portion 5c, and the guide arm 5 moves in the upper left direction in the drawing. Therefore, the guide pin 5a
And the regulation pin 6b is separated from the edge of the CD, and regulation in the ejection direction is removed. Therefore, the eject pin 7b pushes the CD in the ejecting direction (upward in the figure) by the spring force of the eject arm spring 17. By such an operation, the CD shown in FIG. 2 comes out of the opening 3,
From this state, the CD can be removed by hand or the like.

As described above, according to this embodiment, the CD can be directly inserted into and ejected from the storage portion Q without using the disc magazine. Therefore, even when exchanging one CD, it is not necessary to remove the disc magazine from the disc player, and workability and operability are improved.

Further, since the disc magazine is not used, the thickness of the magazine itself and the clearance for loading and unloading the magazine are not required. Therefore, it becomes possible to miniaturize the player. Furthermore, since the disc can be inserted and removed with the minimum number of constituent members, the simplification of the configuration can be promoted.

Further, with respect to the edge of the CD at the storage position, the guide pin 5a, the regulation pin 6b, the eject pin 7 are provided.
Since the CD can be held from the four points, b and the disc contact portion 8, it is possible to accurately position the disc. Although the regulation pin 6b has a double insertion preventing function, the pin 6b may be provided if the function is not required.
It is also possible to omit b and hold the CD only at three points of the pins 5a and 7b and the contact portion 8.

Further, the driving force of the lever 4, the guide arm 5, the control arm 6 and the eject arm 7, which are the main constituent members, utilizes the spring force of the spring that biases each member in one direction. No drive source and drive force transmission system are required. Therefore, it is possible to contribute to simplification of the configuration.

Moreover, in this embodiment, the storage section Q and the reproducing section P are used.
Since and are arranged in an oblique direction, the disc player can be easily downsized as compared with the case where the storage section and the reproduction section are linearly arranged. Further, in this embodiment, since the main constituent members are arranged on the lower surface of the tray T, the recording surface (back surface) of the CD is not damaged by the operation of each member.

The disk accommodating apparatus of the present invention is not limited to the above embodiment, and the shape and size of each member, the number of trays installed, and the like can be appropriately changed. For example, in response to claim 3, there can be mentioned an embodiment in which the storage portion Q having no CD contact portion is adopted. Further, it goes without saying that the present invention is widely used not only in a CD autochanger but also in a disc player.

As described above, according to the disk storage device of the present invention, a disk can be mounted with a simple structure.
In addition, since the disc magazine is not used, it is not necessary to remove the disc magazine from the reproducing device and exchange the discs one by one, and no troublesome labor is required, and excellent workability and operability can be obtained. As a result, the usability of the disc player is improved. Further, the size of the disc player can be reduced by the amount that the disc magazine is not used. Furthermore, since the disc can be inserted and removed with the minimum number of constituent members, it is possible to simplify the configuration. Further, since the disc can be held from at least three points, accurate disc positioning can be performed.
